IMPROVEMENT lN PROCESSES 0F PREPARING THE SURFACE OF WOOD WORK 0F C ARRIAGES.

Specification forming part of Letters Patent No. 175,62], dated April 4, 1876; application filed February 26, 1876.

To all whom it may concern Be it known that I, PATRICK OBRIEN, of South Bend, in the county of St. Joseph and State of Indiana, have invented a new and useful Process for Treating the Wood-Work of Carriages and Cabinetare, which process is fully set forth in the following specification:

My invention relates to certain improvements in'the process of preparing the woodwork of carriages and other vehicles and cab inet-work for the reception of what is known in the art as the final or finishing coat of paint and varnish; and my invention consists in theapplication to the surface of the wood of a preparation of linseed-oil and driers,-heatcd and applied while in a heated condition, for the purpose of hardening the surface and otherwise preparing it for the reception of the final coat of paint and varnish, and avoiding the necessity of the application of a. series of coats of paint, as is at present practiced in the art of finishing such work.

With these objects in view, my invention consists in treating the woodwork of carriages, cabinet-ware, em, previous to painting the same, with a solution of oil and ordinary driers heated to any degree up to the boiling-point, (preferably the latter,) and ap plying the same, while in a heated condition, to the wood with a brush or sponge.

Previous to my invention it has been ens-- of paint and varnish, and protect the wood from the action of the weather. It will be readily understood that this treatment of the wood requires a large expenditure of labor and material, and hence increases the cost. I have discovered that ordinary linseed or paint oil, when mixed with ordinary driers and heated at any degree up to the boiling heat, and applied while in such heated condition to the surface of the wood, thoroughly permeates the fiber of the same and success fully conceals the grain andjoints, and, when dry, furnishes an even and extremely hard surface,-which thoroughly protects the wood from the action of the weather, and which is especially adapted to receive the final coat 0 paint and varnish.

The proportions of. oil and driers to be used will be readily determined by those familiar with mixing and using paints, and will be' governed also by the time allotted to the work to dry, and consequently a variation of the proportions will not, in any sense, he a depar- I coating the surface with a solution of oil and driers in a heated condition, as and for the purposes set forth.

Witness my hand this 21stday of February, A. I). 1876.
